Azure Active Directory

I saw the requirement for Azure AD because of SCIM 2.0. I have 2 questions around this. One, what level of Azure AD is needed? (Basic, P1, P2...). Two, we are currently running Azure AD sync from our on prem AD to O365 for our mail and Office 365. Is there any way for us to piggy back on that to sync to 1Password?

Thanks
